Re: [squid-users] Caching in 3.2 vs 3.1 - solved ?

Hi,

I tried setting a very permissive refresh_pattern - but squid still
refuses to cache.

Then I tried creating a small disk cache. In the real production environment
we use memory cache only.

cache_dir ufs /tmp/3/cache 4 1 1

And now the objects gets cached !

[root_at_sesxsp01wintc 3]# cat access.log
1332337330.903 1 127.0.0.1 TCP_MISS/200 341 GET
http://127.0.0.1:9990/x - HIER_DIRECT/127.0.0.1 text/plain
1332337333.711 0 127.0.0.1 TCP_MEM_HIT/200 348 GET
http://127.0.0.1:9990/x - HIER_NONE/- text/plain

So earlier versions of squid support memory-cache only - 3.2 requires
a disk-cache.
